Supplementary figures and tables for a paper estimating land purchases by 'locals' during the Soma-Yama Seiri forest ownership classification project in modern Okinawa. The materials include lists of historical sources, examples of land transactions ('Haraisage'), excerpts from imperial ordinances, administrative documents, and public notifications from the early 20th century. The dataset was authored by SAITO Kazuhiko and last updated in May 2026.
